Shoe pad

ABSTRACT

A shoe pad includes a flexible board having a series of hollow raised portions formed thereon. Every two adjacent raised portions laterally complementally correspond to each other such that a passage is defined between the two adjacent raised portions. The passage can provides transversely ventilating effect such that the sole of the user would not directly contract with the flexible board and be supported by the series of raised portions for keeping dry and preventing the user&#39;s sole from being infected with Athlete&#39;s foot.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a shoe pad, and more particularly to a shoe pad that can be used as an insole or a footbed, and provides massage and ventilating effects.

2. Description of Related Art

A conventional shoe pad in accordance with the prior art comprises a flat structure and multiple through holes defined in the flat structure for providing ventilating effect. However, the flat sole of the conventional slipper do not provide any massage effect.

The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional shoe pad.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide an improved shoe pad that can be used as an insole or a footbed, and provides massage and ventilating effects.

To achieve the objective, the shoe pad in accordance with the present invention comprises a flexible board having a series of hollow raised portions formed thereon. Every two adjacent raised portions laterally complementally correspond to each other such that a passage is defined between the two adjacent raised portions. The passage can provides transversely ventilating effect such that the sole of the user would not directly contract with the flexible board and be supported by the series of raised portions for keeping dry and preventing the user's sole from being infected with Athlete's foot.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a shoe pad in accordance with the present invention comprises a flexible board (10) having a series of hollow raised portions (11) formed thereon. In the preferred embodiment of the present invention, the raised portions (11) are parallel to one another. Each raised portion (11) has a continual wave-shaped top portion including wave crest(s) (111) and wave trough(s) (112), wherein the wave crest (111) has a width gradually reduced relative to the connected wave trough(s) (112). Consequently, every two adjacent raised portions (11) laterally complementally correspond to each other and a continual curved passage (12) is formed between the two adjacent raised portions (11).

As described above, the curved passage (12) between two adjacent raised portions (11), can provides transversely ventilating effect such that the sole of the user would not directly contract with the flexible board (10) and be supported by the series of raised portions (11) for keeping dry and preventing the user's sole from being infected with Athlete's foot. In addition, the raised portions (11) can be used as cushions for comforting user's sole. Furthermore, the wave troughs (112) communicate with the adjacent curved passages (12) for defined a curved and longitudinal passage (not numbered) that enhances the ventilating effect of the passages (12), the design of wave crests (111) and the wave troughs (112) can promote the friction force between the user's sole and the shoe pad to provide a function of non-slip.

With reference to FIGS. 4 and 5, the shoe pad in accordance with the present invention further comprises a sealant (13) secured on a lower side of the flexible board (10) for airtightly closing the hollow raised portions (11) such that each raised portion (11) forms an airbag for enhancing the absorb effect of the raised portions (11).

With reference to FIGS. 6-8, the sealant (13) has a series of raised portions (131) formed thereon for providing a function as air cushion. In addition, each raised portion (131) of the sealant (13) has a structure the same as that of the raised portion (11) of the flexible board (10). Each raised portion (131) of the sealant (13) aligns and communicates with a corresponding one of the raised portions (11) of the flexible board (10) such that the room of the airbag is enlarged and the absorb effect of the raised portions (11) is enhanced.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed. 

What is claimed is:
 1. A shoe pad comprising a flexible board having a series of hollow raised portions formed thereon, every two adjacent raised portions laterally complementally corresponding to each other such that a passage is defined between the two adjacent raised portions, whereby the passage can provides transversely ventilating effect such that the sole of the user would not directly contract with the flexible board and be supported by the series of raised portions for keeping dry and preventing the user's sole from being infected with Athlete's foot.
 2. The shoe pad as claimed in claim 1, wherein each raised portion has a continual wave-shaped top portion including wave crest(s) and wave trough(s), the wave crest having a width gradually reduced relative to the connected wave trough(s) such that the passage is curved.
 3. The shoe pad as claimed in claim 1 further comprising a sealant secured on a lower side of the flexible board for airtightly closing the hollow raised portion such that each raised portion forms an airbag for enhancing the absorb effect of the raised portions.
 4. The shoe pad as claimed in claim 2 further comprising a sealant secured on a lower side of the flexible board for airtightly closing the hollow raised portion such that each raised portion forms an airbag for enhancing the absorb effect of the raised portions.
